We have observed these bird species regularly at our bird feeder. This is roughly the order that they appeared, and also the relative population except for the Junco which is migratory.

4. A Cardinal family, male sits on feeder, female on the deck
5. Downy Woodpeckers, male and female
6. Purple Finches, male and female.
7. A Carolina Wren started visiting. Later, I saw one foraging in the leafy ground.
8. Mourning doves sit on the deck, building a congregation through the day.
9. In late fall, a Slate-Colored Junco appeared (it's a "race" of Dark-Eyed Junco). After a few months there are half a dozen. The come early and straggle all day, mostly feeding off the crumbs on the deck, but the early birds actually perch on the feeder. I guess their short bills make it hard to poke into the feeder.
10. A Red-Bellied Woodpecker.
